一天应该刷几次牙?专家教你怎样刷牙才对牙齿最好

How often should you brush your teeth? Oral hygiene 'dos and don'ts' explained by expert

It's a habit which has been drummed into us from an early age, but the recent news about flossing your teeth could be a waste of time has put the spotlight on oral hygiene.

我们从幼时就开始培养刷牙的习惯,但最近却有报道称用牙线剔牙纯属浪费时间,这也引发了人们对口腔卫生问题的关注.

When it comes to looking after our teeth, there are certain pieces of wisdom which we've incorporated into our routines.

说起清洁牙齿,其实我们身边存在很多种日常洁牙的方法.

But in the wake of the news about flossing, when it comes to oral hygiene, how much does your average person know about what we should be doing - and which habits do we need to ditch?

但是在有关牙线洁牙无用的报道出来后,人们开始关注口腔卫生问题,但究竟哪些是我们应该做的,又有哪些习惯是我们应该摒弃的?

For example, how many of us know how long we SHOULD brush or teeth for and how often? And what are we doing wrong?

还有一些问题比如,刷牙应该刷多久?多久应该刷一次?我们的哪些行为是错的呢?

MirrorOnline spoke to the British Dental Association's scientific adviser, Professor Damien Walmsley, who kindly put together this definitive list of "dos and don'ts."

《镜报》网站采访了英国牙科协会的科学顾问——达米恩•沃姆斯利教授,他为我们整理出了一份注意事项的清单.

How often? 多久刷一次牙?

"The best way to prevent tooth decay is to brush teeth twice daily with a fluoride toothpaste to remove plaque, limit the frequency, and amount of sugary food and drinks consumed in your diet, and see the dentist regularly.

"预防蛀牙的最好办法就是一天用含氟牙膏刷两次牙,因为含氟的牙膏可以帮助去除牙菌斑,除此以外还需要控制含糖饮食的次数和摄入量,并定期看牙医."

Don'ts 该避免的事:

1. Brush for long enough – research indicates that people only brush for 45 seconds

1. 刷牙时间不要太短.研究发现很多人刷牙只刷45秒左右.

2. Rinse the mouth after brushing – fluoride helps to prevent, control and even stop tooth decay – but rinsing the mouth out dilutes the concentration of fluoride, so SPIT, don't rinse.

2. 刷牙后不要使劲漱口.氟化物能预防、控制甚至让龋洞停止进一步发展,但使劲漱口会稀释氟化物,所以直接吐出来就好了.

3. Brush too soon after eating – as enamel on teeth is softened after eating especially with sugary foods – it's best to wait an hour before brushing which allows the tooth to harden up more.

3. 进食后切勿立马刷牙.进食后——尤其是吃了甜食后——牙釉质会软化,所以最好过一个小时等待牙釉质恢复后再刷牙.
